Hi guys,
Time for some new tyres on the Vantage - looking at Event tyres as they seem pretty highly recommended, and they can do the fitting too. Think I'm going with the Michelin PSS tyres, only doing the rears right now (fronts will get done in a few months), but just want to make sure I'm ordering the right ones! Hoping they'll be quieter than the Bridgestones....
The AM ones are - 275/35R19 96Y BRIDGESTONE POTENZA RE050A BZ AM9
The PSS ones that Event have that match are - 275/35ZR19 96Y MICHELIN PILOT SUPER SPORT LX
Just want to check does anyone know what the LX is at the end?

It's a typo. It should be XL, not LX. The XL has a higher load index than the standard one...
275/35R19 XL = 100Y (800 kg load index, 186+ mph maximum speed)
275/35R19 = 96Y (710 kg load index, 186+ mph maximum speed)
I would *guess* the practical difference is that the XL has a stiffer sidewall to enable the higher load rating.

It's a typo. It's XL which means it has an increased load carrying capacity.
Personally, I'd replace all 4 in one go. Mixing tyres is never really good practice and it can be quite easy to unbalance these cars without too much effort.
Granted, it will be down to the individual's sensitivity and how they are driving, but with temperatures dropping and wet weather approaching, it's worth having four matched boots with as equal tread depth as possible.

Many thanks guys! I thought it might be a typo, although they list that particular tyre as 96Y too. Anyone has any experience of the stiffer sidewall w.r.t noise and feel?
I would replace all 4 at once, but given that my main journey is a rather dull 12 miles on the A4 to work, I think the fronts may well just have to wait a couple of months....

Just to update the thread, I had two Michelin PSS 275/35ZR19 96Y fitted to the rears, VERY happy! Much smoother and less road noise (although I am comparing to the Bridgestones that were at the end of their life). The LX was a typo, as others suspected, and I was very happy with the service I got from Event tyres (I have absolutely no affiliation to them).
Fronts are currently at 4-5mm, but when they're due, I'll be swapping onto the PSS!

Yes, really. If you're just casually cruising around town, you probably won't notice the difference. But in spirited driving or quick maneuvers (say, a high-speed emergency situation), the differences can become apparent.
With extra-grippy tires in the rear, the fronts will lose traction first, resulting in understeer.
With extra-grippy tires in the front, the rears will lose traction first, resulting in oversteer.

Lol nope. But I've driven a number of different types of cars with a number of different types of tires, and driven the same cars with different tires. The changes in vehicle dynamics going from one type of tire to another can be very obvious. To say there isn't a difference is dangerous.I don't assume to know what type of driving burnout3 will be doing, nor can I predict if he'll ever find himself in an emergency situation. But what I do know is that having mis-matched tires can result in a change in the vehicle's handling, and that can be dangerous if the driver doesn't understand that change. Providing a word of caution based on a simple understanding of tires isn't perpetuating an urban myth. It's simply helping another person as they change from one type of tire to another.

I once drove an old Transit hire van with a mixture of cross ply tyre mixed with normal tyres , in the damp as well.I don't assume to know what type of driving burnout3 will be doing, nor can I predict if he'll ever find himself in an emergency situation. But what I do know is that having mis-matched tires can result in a change in the vehicle's handling, and that can be dangerous if the driver doesn't understand that change.

Now that was an interesting experience.
Ps. , just remembered the transit had the old V4 engine , showing my age now.
Point taken about the tyres but I can't help think that you're worrying a tad too much.

Really?????Yet another urban myth that people keep repeating.
The 96 and 96 XL ratings confuse me. I thought 96 was the weight the tyre could take - the higher the number the higher the load it can carry. My Rapide has PSS 99 on the front but only 95 is specified (only load rating they do in this size). No issues I can discern - initial research indicated they may have a slightly stiffer/meatier sidewall. Immediately felt more compliant than stock with better ride and more tenacity on rough surfaces and thus were a huge improvement over AMR approved Bridgestones. Big huge!!
Not sure about other tires, but the ones originally mentioned are rated at 96Y and 100Y. The 100Y has a higher load index, thus the 'XL' being added to the tire's description. Standard are 96Y, XL are 100Y. The XL just helps clarify that although the tires are the same brand, model, and size, one tire has a higher load rating than the other.

Burntout wasn't questioning "mis-matched" tyres he was asking about different (high quality) makes on front and rear axles.For 36 years of my professional career I was a Road Traffic Collision Investigator and attended literally thousands of collisions and I can't remember one single case where tyres of different makes on front/rear axles was a contributory factor.

Is that like saying a 96 XL is like a 96.5 and then the next load rating up is 97 do you think? Not being petty mate as this area always confuses me. Its like me requesting a 36" waist trousers but getting a 36" XL which is in fact a 37"

It isn't a 96Y XL, it's a 276/35R19 XL.The XL is a label, seen here:
Michelin Pilot Super Sport 275/35R19
Michelin Pilot Super Sport 275/35R19 XL
That means these two tires are available:
Michelin Pilot Super Sport, in the size 275/35R19, with a 96Y rating (710 kg load index, 186+ mph maximum speed)
Michelin Pilot Super Sport XL, also in that same 275/35R19 size, but with a 100Y rating (800 kg load index, 186+ mph maximum speed)

I was very pleased to read your phrase, 'Road Traffic Collision'.
Somebody enters a corner at too higher speed for the circumstances. Physics takes over, and their car leaves the road on the outside of the corner, often after the corner exit.
The Police seem to always describe crashes as a 'Road Traffic Accidents'. I have never thought of the circumstances described as an accident. More like inexperience, or negligence.

The PSS are better when worn than the Bridgestones are new.You'll also be fine with Bridgestones front and PSS rear. I ran like this until the fronts ran out and I replaced with PSS.
Telum01 is being very over cautious. Given unlimited funds, replacing all 4 at the same time when swapping brands is the ideal position. But it's not necessary and certainly not "dangerous".
Different makes/models across the axle is, however, an issue...
